PHPFun: ([.^])

Inspired by aemkei/jsfuck and based on splitline/PHPFuck

Using only 6 different characters to write and execute PHP.

Only support PHP 7+ currently.

Demo

The following source will execute phpinfo();:

<?php

Usage

usage: phpfun.py [-h] [-O FILE] [-P] [-E {assert,create_function}] code

positional arguments:
  code                  any string to encode.

optional arguments:
  -h, --help            show this help message and exit
  -O FILE, --output-file FILE
                        write encoded string into some file.
  -P, --plain-string    encode as plain string (without eval it).
  -E {assert,create_function}, --eval {assert,create_function}
                        choose eval mode. (`assert` mode only support PHP < 7.1)

You can just use it like this: python3 phpfun.py "system('id');"

Arguments

• code (required)
  • Any string or php code to encode.
• -O, --output-file
  • Write encoded string into some file.
• -P, --plain-string
  • Encode as plain string (without eval it).
  • With this argument, I will not wrap your code into assert or create_function to eval.
• -E, --eval
  • You can choose your eval mode!
  • create_function mode (default)
    • create_function('', YOUR_CODE)();
  • assert mode
    • Only support PHP < 7.1 (=7.0.x).
    • assert( '(function(){ YOUR_CODE; return 1; })()' );

TODO

• Don't use deprecated feature. (create_function has been DEPRECATED)
• Compatible with PHP 8
• With [^a-zA-Z0-9] and len(set(encoded)) < 6
